MIR-22.1┃Choose sfrxETH collateral parameters on Parallel on Ethereum

Summary:

This proposal aims to set parameters for sfrxETH collateral on Ethereum.

Rationale:

With the recent vote in favor of integrating sfrxETH as new collateral on Ethereum, the DAO needs to set the different parameters of this collateral.

We propose :

• Liquidation Ratio: 140%
• Minimum Collateral Ratio: 150%
• Debt Limit: 100k PAR
• Liquidation Bonus: 8%

We have considered the sfrxETH risk’s assessment to chose these parameters

(You can find out the risk assessment details of this asset in the previous MIR discussion)

These parameters aim to be balanced for the users and the protocol, but they were also chosen in a low-risk way to be able to run experiment parameters on the pool without possible issues for the users and the protocol given the potential smart contract risks that may exist.

Note that these parameters are likely to be changed in the future according to the first data that we will collect.

Means:

• Human resources: If the proposal is accepted, this will need to add these new parameters to the UNI vault’s smart contract
• Treasury resources: No treasury cost

Technical implementation:

1. Add sfrxETH in the ConfigProvider Contract with all parameters decided by the Mimo governance.
2. Set the oracle PriceFeed related to the sfrxETH Contract (Chainlink + Curve EMA & UniV3 TWAP)

Voting options:

• Accept these new parameters
• Against these new parameters
• Abstain
